Regarding Dispose of Connections in Entity Framework

Question

I need your suggestions on the Below implementation.

I'm using Entity Framework for my ASP.NET WEB API Project

my program Flow is: Repository->BusinessLayer->Controller

my Context name is: UtmDataContext

In Repositories I'm using code some thing like this:

    using (SqlConnection objConnection = new SqlConnection(connstr))
    {
        DbCompiledModel compiledModel = UtmCompiledModel.CreateCompiledDataModel(objConnection, schema);
        using (var dataContext = new UTMDataContext(objConnection, compiledModel, true))
        {
            /*Doing some stuff here*/
        }
    }

in the above code schema is a parameter that comes from the user.

my Project requires to have multi-tenant architecture for entity framework. So I'm Building the model and then feeding it to the UtmDataContext object.

But, I doubt that, is entity framework really closing my objConnection?

Can you please help me on this? Please let me know if you need any further information

Thanks In Advance

Answer 1

一旦using {}块中的所有内容都已执行，您的SqlConnection将被关闭并对其进行dispose（）调用。

Answer 2

When using using on an object implementing IDisposable , the compiler interprets the code as having a try/finally block. The finally block calls the Dispose method of the object.
